I need to run an old ATX motherboard on 12V DC batteries instead of the powersupply. I need that for a robotics project.
I know that power supply provides +12V, -12V, +5V, & -5V DC to the motherboard and other components, but I'm little confused about the +12 and -12 issue, I mean can these be directly connected to the +ve and -ve output of the 12V battery??
My question in simple words: How can I run motherboard on 12V battery?
